[0002] At present, with the continuous increase in sales of new energy vehicles, the amount of retired batteries is about to enter a period of rapid growth. The current method of recycling batteries is generally to directly crush and disassemble the lithium batteries. First, the positive electrode, negative electrode, separator and electrolyte are all crushed and mixed together, and then separated and processed in sequence. This method has a low degree of automation, serious pollution and high disassembly cost. Therefore, it is necessary to develop an automated disassembly technology that can non-destructively separate the positive and negative electrodes of batteries. In this disassembly technology, the rewinding and disassembling of the battery cell is one of the key technical points.

[0032] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0033] Please refer to Figures 1 to 5 The present invention provides a lithium battery disassembly device (not shown) for disassembling and recycling lithium batteries. The thermal fuse device 100 therein can quickly and accurately fuse the adhesive tape 310, facilitating subsequent disassembly of the battery cells 300. This device features a high degree of automation, efficient disconnection, and is safe and reliable.

[0034] It should be noted that the lithium battery disassembly equipment includes an electric thermal fuse device 100 and a rewinding and disassembling device (not shown). The electric thermal fuse device 100 is connected to the rewinding and disassembling device; the electric thermal fuse device 100 is used to fuse the tape 310 on the surface of the battery cell 300, that is, to disconnect the end tape 310 at the end of the battery cell 300, facilitating the subsequent rewinding and disassembly of the battery cell 300; the rewinding and disassembling device is used to rewind the battery cell 300 to restore the wound battery cell 300 to a strip shape, facilitating the lossless separation of the positive and negative electrodes of the battery cell 300, reducing environmental pollution, and improving disassembly and recycling efficiency.

[0035] Specifically, the battery cell 300 includes a wound tape (composed of a positive electrode sheet, a negative electrode sheet, and a separator) and a tape 310 attached to the end of the tape. The tape 310 is attached to the middle of the tape and is narrower than the width of the tape itself. The tape 310 is used to prevent the wound tape from unraveling. Therefore, when the thermal fuse device 100 is used to fuse the tape 310, the tape 310 is severed at the end of the tape. Once the tape 310 is severed, the tape can be rewound from the end using the rewinding and disassembly device, allowing the battery cell 300 to be disassembled and recycled.

[0036] The thermal fuse device 100 includes a frame 110, a conveying mechanism 120, a lifting mechanism 130, a mounting frame 140, a heating wire 150, a first driving mechanism 160, a fixing frame 170, a second driving mechanism 180, a lifting frame 190, a photographing mechanism 200, a telescoping mechanism 210, a stopper 220, and a position detection mechanism 230. The conveying mechanism 120 is mounted on the frame 110, and the battery cells 300 are placed on the conveying mechanism 120. The conveying mechanism 120 is used to move the battery cells 300 to a predetermined position. The lifting mechanism 130 is connected to the mounting frame 140 and can move the mounting frame 140 upward or downward. The heating wire 150 is fixedly mounted on the mounting frame 140 and is positioned above the conveying mechanism 120. The position of the heating wire 150 corresponds to the predetermined position of the battery cells 300. The lifting mechanism 130 is used to drive the heating wire 150 downward in a predetermined direction via the mounting bracket 140, so that the heating wire 150 contacts the battery cell 300 and melts the adhesive tape 310 on the surface of the battery cell 300. This allows the heating wire 150 to quickly and accurately melt the adhesive tape 310, facilitating subsequent disassembly of the battery cell 300. This provides a high degree of automation, efficient disconnection, and safety and reliability.

[0037] It should be noted that the first drive mechanism 160 is mounted on the frame 110 and connected to the fixing frame 170. The first drive mechanism 160 is used to drive the fixing frame 170 to move in a first direction. The lifting mechanism 130 is mounted on the fixing frame 170. The first direction is perpendicular to the preset direction. The first drive mechanism 160 can drive the lifting mechanism 130 to move in the first direction through the fixing frame 170, thereby driving the mounting frame 140 and the heating wire 150 to move in the first direction, thereby achieving the displacement function of the heating wire 150 in the first direction, thereby facilitating the alignment of the heating wire 150 with the disconnection position of the adhesive tape 310.

[0038] Furthermore, the lifting mechanism 130 is connected to the lifting frame 190, and the second drive mechanism 180 is mounted on the lifting frame 190 and connected to the mounting frame 140. That is, the lifting mechanism 130 is connected to the mounting frame 140 via the lifting frame 190 and the second drive mechanism 180. The second drive mechanism 180 is used to drive the heating wire 150 to move in the second direction through the mounting frame 140, thereby achieving the displacement function of the heating wire 150 in the second direction, thereby facilitating the alignment of the heating wire 150 with the disconnection position of the tape 310. Specifically, the first direction, the second direction, and the predetermined direction are perpendicular to each other, so that the heating wire 150 can be moved to various positions in the three-dimensional coordinate system, ensuring the accuracy of the heating wire 150 fusing the tape 310.

[0039] In this embodiment, the shooting mechanism 200 is installed on the mounting frame 140 and is electrically connected to the lifting mechanism 130, the first driving mechanism 160 and the second driving mechanism 180. The shooting mechanism 200 is used to capture image information of the battery cell 300 and control the lifting mechanism 130, the first driving mechanism 160 and the second driving mechanism 180 to adjust the position of the heating wire 150 according to the image information to ensure that the position of the heating wire 150 is aligned with the disconnection position of the tape 310, and the distance between the heating wire 150 and the tape 310 is a preset distance.

[0040] Specifically, after the shooting mechanism 200 controls the lifting mechanism 130, the first driving mechanism 160 and the second driving mechanism 180 to complete the position adjustment of the heating wire 150, the heating wire 150 is energized to increase its temperature, and the lifting mechanism 130 is used to drive the heating wire 150 to descend. The descending height can be fine-tuned according to the preset distance to ensure that the heating wire 150 can effectively fuse the tape 310 of different types of battery cells 300, and prevent the heating wire 150 from damaging the tape after passing through the tape 310.

[0041] It should be noted that the diameter of the heating wire 150 ranges from 0.001 mm to 0.1 mm. A reasonable diameter of the heating wire 150 ensures that the heating wire 150 does not easily break and prevents damage to the material strip after melting the adhesive tape 310. In this embodiment, the diameter of the heating wire 150 is 0.05 mm, but this is not limited to this. In other embodiments, the diameter of the heating wire 150 can be 0.001 mm or 0.1 mm. There is no specific limitation on the diameter of the heating wire 150.

[0042] Furthermore, the melting point of the adhesive tape 310 ranges from 100°C to 120°C, and therefore the temperature of the heating wire 150 ranges from 100°C to 180°C. A reasonable temperature of the heating wire 150 can quickly and effectively melt the adhesive tape 310 and prevent the material from catching fire due to excessive temperature. In this embodiment, the temperature of the heating wire 150 is 120°C, and the heating wire 150 is connected to a thermostat, which can accurately and reliably regulate the temperature of the heating wire 150. However, this is not a limitation. In other embodiments, the temperature of the heating wire 150 can be 100°C or 180°C, and there is no specific limitation on the temperature of the heating wire 150.

[0043] Mounting bracket 140 includes a first extension portion 141, a connecting portion 142, and a second extension portion 143, which are sequentially connected. In this embodiment, first extension portion 141, connecting portion 142, and second extension portion 143 are integrally formed to enhance connection strength. First extension portion 141 and second extension portion 143 are disposed on opposite sides of connecting portion 142 and are both located below connecting portion 142. Heating wire 150 has one end connected to first extension portion 141 and the other end connected to second extension portion 143. The first extension portion 141 and second extension portion 143 work together to straighten heating wire 150, facilitating its fusing of adhesive tape 310.

[0044] In this embodiment, the conveying direction of the conveying mechanism 120 is a first direction, and the extending direction of the heating wire 150 is a second direction. The extending direction of the heating wire 150 is perpendicular to the preset direction and also perpendicular to the first direction. During the process of the thermal fuse device 100 fusing the adhesive tape 310, the conveying mechanism 120 conveys the battery cell 300 to a preset position along the first direction. The heating wire 150, under the action of the lifting mechanism 130, descends along the preset direction and contacts the adhesive tape 310 on the battery cell 300, thereby breaking the adhesive tape 310 along the second direction.

[0045] The conveying mechanism 120 includes a driving motor 121, a driving wheel 122, a driven wheel 123 and a transmission belt 124. The driving motor 121 is installed at one end of the frame 110 and is in transmission connection with the driving wheel 122. The driving motor 121 is used to drive the driving wheel 122 to rotate. The driving wheel 122 is connected to the driven wheel 123 through a transmission belt 124. The driven wheel 123 is rotatably installed at the other end of the frame 110. The transmission belt 124 extends along a first direction. The transmission belt 124 is used to place the battery cell 300. The driving wheel 122 can drive the driven wheel 123 to rotate through the transmission belt 124. During this process, the transmission belt 124 drives the battery cell 300 placed thereon to move along the first direction until the battery cell 300 moves to a preset position.

[0046] It should be noted that the telescopic mechanism 210 is mounted on the frame 110 and connected to the stop block 220. The telescopic mechanism 210 is used to drive the stop block 220 to extend above the conveying mechanism 120 to stop the battery cell 300 at a preset position, thereby achieving the positioning function of the battery cell 300. Specifically, the telescopic mechanism 210 can drive the stop block 220 to extend and retract along the second direction. When the stop block 220 extends above the conveying mechanism 120 along the second direction, the stop block 220 can stop the battery cell 300 to ensure that the battery cell 300 stays at the preset position and does not deflect. When the stop block 220 retracts along the second direction, the stop block 220 no longer stops the battery cell 300, and the battery cell 300 can be moved to the next workstation under the drive of the conveying mechanism 120.

[0047] In this embodiment, there are two telescopic mechanisms 210 and two stop blocks 220. The two telescopic mechanisms 210 are relatively arranged on both sides of the conveying mechanism 120. Each telescopic mechanism 210 is connected to a stop block 220. The two telescopic mechanisms 210 are started at the same time to drive the two stop blocks 220 to move closer to or away from each other. The two stop blocks 220 work together to improve the stopping effect on the battery cell 300, and further prevent the battery cell 300 from continuing to move forward or deflecting.

[0048] Furthermore, a position detection mechanism 230 is mounted on the frame 110 and is electrically connected to both the telescopic mechanism 210 and the conveying mechanism 120. Upon detecting that the battery cell 300 has reached a predetermined position, the position detection mechanism 230 controls the telescopic mechanism 210 to extend the stop block 220 and to pause the conveying mechanism 120, thereby ensuring that the battery cell 300 remains in the predetermined position. In this embodiment, the position detection mechanism 230 is an infrared sensor, but is not limited thereto. In other embodiments, the position detection mechanism 230 may also be an ultraviolet sensor. The type of position detection mechanism 230 is not specifically limited.

[0049] Specifically, in the conveying direction of the conveying mechanism 120, the position detection mechanism 230 is located in front of the telescopic mechanism 210. In the process of the conveying mechanism 120 conveying the battery cell 300, when the battery cell 300 begins to pass through the position detection mechanism 230, the position detection mechanism 230 controls the telescopic mechanism 210 to drive the stop block 220 to extend; when the battery cell 300 completely passes through the position detection mechanism 230, the position detection mechanism 230 controls the conveying mechanism 120 to pause. At this time, the conveying mechanism 120 no longer drives the battery cell 300 forward, and the stop block 220 stops the battery cell 300 to ensure that the battery cell 300 stays at the preset position.

[0050] In this embodiment, the lifting mechanism 130, the first drive mechanism 160, the second drive mechanism 180 and the telescopic mechanism 210 are all pneumatic cylinders, but are not limited to this. In other embodiments, the lifting mechanism 130, the first drive mechanism 160, the second drive mechanism 180 and the telescopic mechanism 210 can all be hydraulic cylinders or electric push rods. There is no specific limitation on the driving mode of the lifting mechanism 130, the first drive mechanism 160, the second drive mechanism 180 and the telescopic mechanism 210.

[0051] It is worth noting that during the operation of the electric thermal fuse device 100, the conveying mechanism 120 is first used to feed the battery cell 300 forward; when the battery cell 300 moves to the preset position, the position detection mechanism 230 controls the conveying mechanism 120 to pause, and controls the telescopic mechanism 210 to drive the stop block 220 to extend to stop the battery cell 300, so that the battery cell 300 stops at the preset position; then the shooting mechanism 200 controls the lifting mechanism 130, the first driving mechanism 160 and the second driving mechanism 180 to adjust the position of the heating wire 150, so that the heating wire 150 is located between the adhesive tape 31 of the battery cell 300 and the adhesive tape 31 of the battery cell 300. 0, and the spacing between the heating wire 150 and the tape 310 is a preset distance; then the lifting mechanism 130 is used to drive the heating wire 150 to descend until the heating wire 150 melts the tape 310, and the tape 310 disconnection operation is completed; then the lifting mechanism 130 is used to drive the heating wire 150 to rise, the conveying mechanism 120 continues to start, and the telescopic mechanism 210 drives the stop block 220 to retract, so as to send the battery cell 300 to the next station, and send the next battery cell 300 to the preset position, and repeat this process to achieve the melting of the tapes 310 of multiple battery cells 300, with high disconnection efficiency.

[0052] The thermal fuse device 100 provided in an embodiment of the present invention comprises a conveying mechanism 120 mounted on a frame 110. The conveying mechanism 120 is used to transport the battery cell 300 to a preset position. The lifting mechanism 130 is connected to a mounting frame 140. The heating wire 150 is fixedly mounted on the mounting frame 140 and disposed above the conveying mechanism 120. The lifting mechanism 130 is used to drive the heating wire 150 downward in a preset direction via the mounting frame 140, so that the heating wire 150 contacts the battery cell 300 and fuses the adhesive tape 310 on the surface of the battery cell 300. Compared to the prior art, the thermal fuse device 100 provided by the present invention, due to its use of the conveying mechanism 120 mounted on the frame 110 and the heating wire 150 connected to the lifting mechanism 130 via the mounting frame 140, can quickly and accurately fuse the adhesive tape 310, facilitating subsequent disassembly of the battery cell 300. The device has a high degree of automation, high disconnection efficiency, and is safe and reliable. This results in high efficiency and effective disassembly of the lithium battery disassembly equipment.
